Fault Description Cause of Failure Solution

OTDR will not turn on. The battery is dead. Charge the battery and observe the charging

indicator. If the red light is displayed, continue

charging.

OTDR cannot be charged normally. Ambient temperature not within acceptable

levels.

Replace charger. Try charging the OFL100 with

the USB port.

Check that the charger is working. Set range to greater than the length of the ber.

OTDR does not measure and display

test results.

OTDR parameters are not set correctly. Set range to greater than the length of the ber.

OTDR bulkhead is contaminated. Clean OTDR bulkhead and eld ber ferrule.

OTDR bulkhead is damaged. Send to Vista for bulkhead repair.

Optical output connector mismatch. Use correct ber size and connector to match

bulkhead.

The noise of test curve is excessive,

and the waveform is not smooth.

The eld ber is not connected properly to

the bulkhead.

Clean and reconnect the eld ber to the bulk-

head.

The pulse width setting is too small. Increase the test pulse width.

Averaging time is set too low. Increase the averaging time.

Events are saturated. The pulse width is too long. Decrease test pulse width.

The last connector is open and likely a at

polished connector.

Terminate the last connector or place a Mandrel

wrap on the ber before the last connector.

After a reective event there is a long

tail.

OTDR bulkhead is contaminated. Clean OTDR bulkhead and eld ber ferrule.

OTDR bulkhead is damaged. Send to Vista for bulkhead repair.

The reection peak at the end of the

ber cannot be measured.

OTDR parameters are not set correctly. Set range to greater than the length of the ber.

The pulse width is too short. Increase the test pulse width.

False positive in curve analysis. Event threshold setting is too low. Increase the threshold analysis setting.
